Nucleus pulsosus is derived from ?

Ans. is 'c' i.e., Notochord Development of veebral columnThe human nervous system develops from neuroectoderm.During development, behind the neuroectoderm lies the mesoderm (paraxial mesoderm) that encloses the notochord (a derivative of endoderm).This paraxial mesoderm give rise to somites.Somites fuher differentrated intoDermatomyotome :- Give rise to skeletal muscles and dermis.Sclerotomes :- Give rise to veebral column.Sclerotomes which surround notochord stas projecting posteriorly (dorsally) to surround neural tube and forms.Ventral sclerotomes :- Give rise to veebral body and annulus fibrosus.Lateral sclerotomes :- Give rise to veebral arch (pedicle and lamina).Dorsal sclerotomes :- Give rise to spinous process.The notochord forms the nucleus pulsosus.
